HP Enterprise 454274-001 Internal Hard Drive, 3.5", 450GB SAS

HP Enterprise 454274-001 Internal Hard Drive

The HP Enterprise 454274-001 is a high‑performance, enterprise‑grade internal hard drive designed for demanding server environments. With a capacity of 450 GB, it strikes an optimal balance between storage density and performance, making it ideal for virtualized workloads, database servers, and high‑throughput applications.

Key Technical Specifications

• Form Factor: 3.5‑inch Large Format (LFF), measuring 8.9 cm in diameter, which is the standard size for rack‑mounted servers.
• Interface: Serial Attached SCSI (SAS) 6 Gb/s. SAS offers dual‑port connectivity, allowing simultaneous access from two controllers and providing redundancy for fault tolerance.
• Rotation Speed: 15,000 RPM, delivering rapid data access times and high throughput suitable for enterprise workloads.
• Cache: 512 KB on‑disk cache to accelerate read/write operations and reduce latency.
• Hot‑Swap Capability: The drive is designed for hot‑swappable installation, enabling maintenance without shutting down the server or disrupting services.
• Operating Temperature: Typically ranges from 0 °C to +70 °C, ensuring reliable operation in data center environments.
• Power Consumption: Optimized for low power draw, which helps reduce overall data‑center energy costs.

Performance Highlights

The combination of a high rotation speed and SAS interface results in impressive performance metrics:

• Sequential Read/Write Speeds: Up to 400 MB/s, enabling fast data transfer for large files and backups.
• Random I/O Performance: Capable of handling thousands of I/O operations per second (IOPS) at low latency, which is critical for database transactions and virtual machine workloads.
• Reliability: Designed with enterprise‑grade firmware that includes error correction and self‑healing capabilities to maintain data integrity over long periods of operation.

Enterprise Features

The HP Enterprise 454274-001 incorporates several features tailored for business use:

• Dual‑Port SAS: Provides two independent connections to the host bus adapter (HBA), allowing for load balancing and failover.
• Hot‑Plug Support: Enables replacement of a failed drive without powering down the server, minimizing downtime.
• Advanced Firmware: Supports features such as SMART monitoring, predictive failure analysis, and firmware updates over the network.
• Compatibility: Fully compatible with HP’s ProLiant servers and other SAS‑enabled platforms from major vendors.

Use Cases

This drive excels in a variety of scenarios where performance, reliability, and scalability are paramount:

• Virtualization Platforms: Ideal for VMware ESXi, Microsoft Hyper‑V, or KVM hosts that require fast storage for virtual machine images.
• Database Servers: Supports high transaction rates in SQL Server, Oracle, or PostgreSQL deployments.
• High‑Performance Computing (HPC): Provides the necessary throughput for scientific simulations and data analysis workloads.
• Enterprise Storage Arrays: Can be integrated into RAID configurations to build fault‑tolerant storage solutions.

Installation and Maintenance

Installing the HP Enterprise 454274-001 is straightforward for IT professionals familiar with server hardware. The drive’s hot‑swap feature allows it to be inserted or removed while the system remains operational, provided that the host controller supports SAS hot‑plugging.

• Mounting: Secure the drive in a compatible 3.5‑inch bay using the supplied mounting brackets.
• Connection: Attach one of the dual SAS ports to an available HBA port; the second port can be used for redundancy or load balancing.
• Firmware Updates: Use HP’s management tools (e.g., iLO, HPE OneView) to check firmware status and apply updates as needed.
• Monitoring: Leverage SMART data and system logs to track health metrics such as temperature, spin‑up time, and error counts.

Conclusion

The HP Enterprise 454274-001 Internal Hard Drive is a robust, high‑performance storage solution engineered for the most demanding enterprise environments. Its combination of 450 GB capacity, 15,000 RPM speed, dual‑port SAS connectivity, and hot‑swap capability makes it an excellent choice for servers that require rapid data access, reliability, and minimal downtime.
